Like reference characters refer to like parts throughout the various gures. v

The embodiment of my invention illustrated in the drawings includes a frame I0 having a plurality of successively arranged aligned rollers il, Il rotatably mounted therein between opposite side walls thereof, and so arranged that the metal going through the machine alternately passes under one roller, and over the next successive roller to permit brushing of both sides of the metal. The engaging faces of said rollers are herein shown as being of a resilient material such as rubber, to prevent said rollers from damaging the metal as it passes through the machine.

Brushing of the metal is effected by means of a plurality of power driven rotary brushes I2, I2 alternately arranged along said frame so they may brush the metal as it passes over or under respective'of said rollers. Said brushes are herein shown as being wire brushes mounted alternately towards the upper and lower sides of said frame so that certain of said brushes are disposed beneath the rollers having the metal passing thereunder and certain other of said brushes opposite sides of the sheet and is not herein shown or described since it is no part of my present invention.

With reference now in particular to the rollers II, II and the means for adjustably mounting them in the frame I0, each of said rollers is mounted on a transverse shaft I4 which is journaled at its ends in bearing boxes I5, I5 which are slidably guided in vertically extending guides I6, I6 provided in opposite side walls I1, I1 of said frame. Since each of said rollers is of a similar construction and is mounted in the frame IU in a similar manner, with the exception that the adjusting mechanism for the rollers disposed above the brushes I2, I2 is disposed at the upper side of said frame while the adjusting mechanism for the rollers disposed beneath the brushes I2, I2 depends from said rollers, the same part numbers will be applied to like parts of the rollers and the adjusting mechanism therefor. and the construction of the adjusting mechanism for one roller only need herein be described in detail.

A threaded member'l is secured to each bearing box I 5 and projects upwardly from the rollers having the metal trained thereunder and downwardly from the rollers having the metal trained thereover (see Figures 2, 4, 6, and 7). Said threaded member is threaded within a nut I9 herein shown as being a. sleeve mounted in a housing 20. which is secured to and projects outwardly from the side wall I1 of the frame I0. Said sleeve is rotated by means of a worm gear 2| secured thereto and driven by a worm 22 on a transversely extending shaft 23. Said worm and worm gear are enclosed in the housing 20. In Figures 6 and 7, the threaded member I8 is shown as projecting above said housing and is encircled by a compression spring 25, one end of which spring abuts the upper outer side of said housing, and the opposite end of which spring abuts a collar 21. Said collar is held from upward movement with respect to said shaft by means of suitable lock nuts 29, 29. Said compression spring has as its function to take up any play which might be present between the threads of said nut and threaded member. Suitable hand wheels 30, 30 on the outer end of transverse shafts 3|, 3| are provided to adjustably move the upwardly projecting threaded members I8. The shafts 3|, 3| are mounted in opposite side walls I1, I1 and in the housings 20, 20, and are connected with the shafts 23, 23 on opposite sides of said frame by means of chain and sprocket drives. disposed within said housings and generally indicated by reference characters 32, 32.

The depending threaded members I8 are vertically adjusted by means of hand wheels 33, 33 on the ends of transversely extending shafts 34, 34. Each of said shafts has the worms 22, 22 directly mounted thereon adjacent opposite ends thereof. 'I'he reasonfor the difference in arrangement of the adjusting mechanism between the rollers disposed above the brushes I2, I2 and beneath said brushes is to permit the transverse shafts 3|, 3| to beoiset from the respective rollers which they serve to adjust to permit all of the rollers to be lifted vertically from the frame III.

It should be understood that the rollers II, II are idler rollers only and rotate at a relatively slow rate of speed, forming a means for backing up the metal while it is being brushed by the brushes I2, I2 and forming a means for adjusting the depth of the brushing operation.

The brushes I2, I2, as herein shown, are of a usual construction and include wire bristles 31 spirally wound on a transverse shaft 35 and secured to said shaft by means of clamping members 36, 36 engaging the ends of a spiral wire from which said bristles project (see Figure 8). The transverse shaft 35 is journaled in one side frame member I1 in a bearing support member 39 on a roller bearing 4.I. The outer periphery,

of said bearing support member is of a frusto'- conical formation and is adapted to engage an opening 40 of a similar formation, formed in one side wall I1. Said roller bearing is so constructed as to permit said shaft and the brush I2 to reciprocably move laterally with respect to the frame I0.

A bearing support member 43 is provided to journal the shaft35 in the opposite side wall |1. Said bearing support member has an outer peripheryof a frusto-conical formation which is adapted to engage a corresponding opening 42 formed in said respective side frame member. Said last named opening is of a larger diameter than said first named opening to permit the bearing support member 39 to pass therethrough. A roller bearing 44 is mounted in the bearing support member 43 and forms a bearing for said transverse shaft. Said roller bearing is likewise arranged to permit lateral movement of said shaft with respect to the fr'ame I 0.

A projecting end 45 of the transverse shaft 35 forms an armature shaft for a motor 4S, which motor is provided to rotatably drive said brush. Said projecting end is journaled in an end plate 41 of a housing 48 for said motor to permit end- Wise movement with respect thereto, which housing is herein shown as being formed integral with the bearing support member 43.

The means for reciprocably moving the shafts 35, 35 and brushes I2, I2 laterally with respect to the frame Ill includes a motor 49 mounted on a bracket 50 projecting laterally from the side wall I1 opposite from the motors 46, 4B (see Figures 1 and 3). The motor 49, as herein shown, has direct connection with a speed reducer 5| for driving said speed reducer. A crank 53 is rotatably driven from said speed reducer and has a link 55 pivotally connected thereto. A link 56 is pivotally connected to said crank on a pivotal pin 51. Said link extends angularly upwardly from said link and crank and forms a means for reciprocably moving the upper brushes I2, I2 transversely of the frame IU. A link 59 is likewise pivotally connected to the link 55 on the pin 51 and extends angularly downwardly from said crank and forms a means for reciprocably moving the lower brushes I2, I2. The link 56 has pivotal connection with a link 60 which extends along the frame I0 and has a plurality of rocking arms 6I, 6I pivotally connected thereto at intervals therealong.

Each arm 6|, as herein shown, is secured to an externally threaded member 63 for rocking said threaded member. A bearing 64 is mounted in said threaded member and held from movement with respect thereto by means of a cap 65 members 86: 66, Within which they are threaded.

The pitch of the threads of said threaded members may be varied where it is desired to increase or decrease lateral movement of the brushes.

'I'he link 59 has pivotal connection with an end of a link 69 extending longitudinally of the frame I0 and having pivotal connection with rockingr arms 6|, 6I, for reciprocably moving the lower brushes in a manner similar to the manner in which the upper brushes are reciprocably moved. Thus as the brushes I2, I2 are rotatably driven by the respective motors 46, 46, they will be simultaneously reciprocably moved across the face of the metal to provide a more uniform brushing action on the surface of the metal and provide a more accurate means for surfacing the metal and attaining the desired nish.

With reference now in particular to the novel means for mounting the brushes I2, I2 in the frame I0 so they may readily be inserted or removed for inspection or repair without the danger of damaging the brushes while being inserted or removed from the machine, a pair of parallel spaced horizontal guide members 1I, 1I are mounted at their ends in opposite sides of the apertures 40 and 42 and extend across the side frame members I1, I1 of the frame II] (see Figures 5, 8 and l0). Each of said guide members is mounted in the frame I0 between a pair of spaced angles 12, 12 secured to and projecting inwardly from the inner sides of the side walls I1, I1.

The end bearing support member 39 is provided with a pair of oppositely disposed grooved guides which are adapted to engage the guide members 1I 1I so said guides may form a means along which said bearing support member may slide for guiding the brush as it is insertedin the frame, to permit its ready insertion, and to prevent dropping or injury to the brush during insertion or removal from the machine. The bearing support member 43 is likewise provided with a pair of oppositely disposed grooved guides adapted to have engagement with the guide members 1I for guiding said bearing support into the aperture 42 and preventing turning movement thereof.

The bearing support member 43 and motor 46 are held in position in the frame I0 by means of a pair of clamping members 13, 13 (see Figures 8 and 9) mounted on bolts 14, 14 projecting from the side frame member I1, adjacent the motor 48. Said clamping members extend within suitable openings formed in the casing 48 for the motor 46 and are adapted to engage the inner side of the bearing support member 43. A compression spring encircles each bolt 14 and is interposed between the outer side of the frame I0 and the inner side of the clamping member 13 to tend to move said clamping member to a disengaged position with respect to said bearing support member. Suitable lock nuts are threaded on the ends of said rods for holding said clamping members in engagement with said bearing support member.

The bearing support member 39 is held in the opening 4I! by means of clamping members 16,16 mounted on the inner side of the side frame member I1 opposite from the motor 46, and engaging slotted guides 11, 11 formed in the inner face of said bearing support member (see Figures 8 and 10). Each of said clamping members is engaged with said bearing support member by means of a threaded rod 18 extending through the side frame member I1 and threaded in said clamping member (see Figures 8 and l0). A handle 19 is provided on the outer end of said rod, for rotating said rod, and a lock nut is provided for locking said rod from rotation. A compression spring 8I is likewise interposed between the side frame member I1 and the clamping member 16 to tend to move said clamping member to a disengaged position with respect to said bearing support member upon rotation of the threaded rod 18 in a direction to release said clamping member.

Means are provided to hone the wire brushes I2, I2 and insure that the diameter thereof be uniform which as herein shown comprise hones 83, 83 (see Figure 4). Each of said hones includes a honing stone 84 formed of a suitable honing material such as an oil or carborundum stone, or any other such material. Said honing stone is mounted in and projects from an adjustable carrying member 85. Said carrying member is provided with spaced side wall members 81, 81 extending in a direction away from the honing stone and brush I2. The inner sides of said side wall members slidably engage opposite sides of a guide and support bracket 88. A connecting member 89 is provided to connect said side wall members together. Compression springs 90, 90 are interposed between said connecting member and said guide and support bracket in such a manner as to tend to move the honing stone 84 away from the respective brush I2.

The inner side of the member 85 is provided with a pair of spaced notches 9|, 9I having inclined surfaces adapted to be ,engaged by projecting inclined surfaces 93, 93 of an adjusting member 94, which is guided between the side walls 81, 81 for lateral movement withrespect to the support bracket 88. Said adjusting member has an outwardly projecting rod 95 threaded therein which has a worm gear 96 secured to its outer end.` A worm 91 is meshed with said worm gear and is rotated by means of a hand wheel 99.

It will be obvious from the foregoing that rotation of said hand wheel and the rod 95 will move the adjusting member 94 laterally with respect to the frame I8 which in turn will elevate or lower the honing strone 84 by engagement of the inclined engaging surfaces 93, 93 with the corresponding inclined surfaces of the notches 9|, 9| to bring said stone into engagement with the brush I2, for honing said brush.

In Figures 1l to 14, inclusive, a honing apparatus separate from the brushing machine is provided for honing the brushes I2 on the same centers as when in the machine. The details of the brush, and hone and support'therefor, are the same as have hereinbefore been described, so the same part numbers will be applied to similar parts shown in these figures, as were applied in Figures 1 to 10, inclusive.

A honing stand |09 is provided which includes a base I I0 and a pair of side frame members II I, III having frusto-conical apertures II2 and II3 formed therein for receiving the bearing support the brushing machine together with the motor 46 and said motor rotatably drives said brush during honing. .Said brush is reciprocably moved during the honing operation by means of a mo- -tor ||4 mounted on the base ||0 and driving a speed reducer II5. A crank IIB is rotatably driven by said speed'reducer and said crank reciprocates the brush by means of a link I1 having pivotal connection with the rocking arm 6|. The honing stone is adjustably moved towards or away from the brush by means of the hand wheel 99. Since the brush I2 is mounted in the honing stand on the same bearing support member which supports itin the machine, it may be accurately ground in the honing apparatus, separate from the machine. With such an arrangement spare brushes may be ground and trued up and made ready to insert in the machine when necessary.

A suitable means is provided to protect the brushes I2, I2 when inserted in or removed from the frame I or honing stand |09, which comprises a hinged cylindrical casing ||9 adapted to completely encase each brush (see Figures 13 and 14). Said casing, as shown in Figure 14, is provided with an outwardly and upwardly extending projection |20 from one side of said hinged casing which is adapted to extend through an outwardly projecting end I2I of the opposite side of said casing. A wedge |22 extending through an opening formed in the projecting end |20 and engaging the projecting end I2I of said casing is provided to lock said casing in a closed position. The projecting end I2I is provided with an opening |23 adapted to receive a hook for lifting said brush, as is best shown in Figure 13.

In removing the brush from the brushing machine or the honing stand,.the clamping members 13, 13 and 16, 16 are released from the bearing support members 43 and 39 respectively, and a crane or other suitable lifting mechanism is connected to the motor 46 by means of a chain but before said bearing support member is disconnected therefrom, the brush is covered by the hinged casing |I9 in the hereinbefore described manner. Said casing is then closed and a chain |25 is connected to the projecting end I2I of said cover (see Figure 13). The entire brush may then be removed from the machine.

When inserting the brush in the machine or into a separate stand for honing, it is covered by the casing IIS until the guides in the end bearing support member 39 are engaged with the guide members 1I, 1|. The chain |25 is then disconnected from said casing and said casing is removed from the brush. The entire brush may then be slid into the machine or honing stand along the guides 1 I, 1

It will be seen from the foregoing that a new and improved precision brushing apparatus has been provided for finishing continuous strips of sheet metal, that said brushing apparatus is so arranged that the brushes and their power drive units may readily be inserted or removed from the machine frame as units for inspection or -membersj39 and 43. The brush is removed from repair, that the construction of the support means and. their power drive units for said brushes is so arranged as to prevent damage to the brushes during insertion or removal from the frame, by providing guides for positively guiding the brushes into position and by providing a cover for the brushes upon removal from the frame,v and that the brush assembly is so arranged as to permit honing or grinding of the brushes separate from the machine on the same centers about which they rotate while in the machine. l

While I have herein shown and described one form in which my invention may be embodied, it will be und erstood that the construction thereof and 'the arrangement of the various parts may be altered without departing from the spirit and scope thereof.
